Description

Technical Field

[0001] The utility model relates to the technical field of rail grinding, in particular to a rail grinding mechanism used for railway transportation. Background Art

[0002] As an important national transportation system, the development of railway track maintenance technology is closely related to the development of railways themselves. China's railways have a history of more than 140 years since the opening of the Shanghai-Wusong Railway in 1876. During this long history, railway track maintenance technology has undergone a transformation from manual operation to mechanization and then to modern intelligent maintenance.

[0003] In the mid-20th century, with the advent of mechanized inspection technology, the efficiency of track maintenance work was significantly improved. In the 1960s, the application of computer technology made the data processing speed of track inspection equipment faster and more accurate. By the 1980s, track inspection technology had become very mature.

[0004] Entering the 21st century, with the development of high-speed railways, higher requirements have been put forward for track maintenance technology. On the road of "introducing, absorbing, digesting and re-innovating", China Railway has successfully "transformed" from a follower to a leader. In 2017, the Fuxing high-speed train with completely independent intellectual property rights was put into operation, marking the maturity and leading position of China's high-speed railway technology.

[0005] In terms of track maintenance, China Railway uses large-scale track maintenance machinery to carry out a series of maintenance operations such as tamping maintenance, rail grinding, and fastener maintenance to ensure the safe, stable and efficient operation of trains. Traditional track grinding methods usually require a lot of manpower and material resources, are inefficient and costly. Therefore, it is particularly urgent to develop a track grinding mechanism with a high degree of automation, simple operation and low maintenance cost.

[0006] In summary, the development of railway track maintenance technology not only reflects the progress of the railway transportation industry, but also reflects the profound impact of scientific and technological progress on railway maintenance work. The track grinding mechanism of the utility model is intended to further improve the maintenance efficiency and quality of railway tracks. Utility Model Content
